基于目标机动检测的集成估计与制导方法

基于传统的估计器和制导律独立优化设计方法在实际的目标拦截情形中如有界控制、饱和状态变量等其综合性能不是最优，同时目标机动估计延迟对拦截导弹寻的性能具有较大影响，将估计器和制导律集成考虑，给出一种适用于随机机动目标拦截的自适应集成估计与制导方法。该方法主要由滤波器组、制导律组和1个目标机动命令切换时间检测器构成。检测器为广义似然比检测器，对目标机动特征如目标机动突变时间和突变量等进行检测，并由检测时间对滤波器和制导律进行在线选择，从而削弱估计延迟对导弹寻性能的影响。基于Monte Carlo试验法进行仿真。研究结果表明：该集成估计和制导设计方法与具有单一滤波器和制导律的方法相比，可有效提高导弹单发命中概率。

Integrated estimation and guidance approach based on target maneuver detection

Based on the fact that in the actual target interception scenario,for example,bounded control and saturated state variables etc,the comprehensive properties of the traditional independent optimization methods of estimator and guidance law design are not optimal,and based on the performance analysis of differential game guidance law and shaping filter for random target maneuver modeling,the homing performances of interception missiles corresponding to different guidance laws and shaping filters are affected ...
